The Back garden in Wanggung-ri Site, Iksan clearly presents an aspect of the landscape gardening techniques of the Baekje, which are significantly unique in the landscape gardening history of East Asia as the structure connected to the main garden through a complex waterway system on a hill. The rear garden has a complex waterway system comprising a large inverted U-shape waterway and its branch waterways, sinuous waterway and water catchment system to enhance the landscape effect with a minimum amount of water on a hill, reducing damage by floods in the case of heavy rain and securing the amount of water required by the main space in the palace. A landscape element using various kinds and sizes of oddly shaped rocks decorated the water catchment area inside or around the large inverted U-shape waterway. On the top of the hill, the center in the Back garden, a building site in the size of 4 Kans each on the front and side was made on a square base surrounded by a round base stone. The building was identified on a space partially surrounded by the rectangular stonework on the left and right slope of the hill. While the functions and roles of the rectangular stonework are not accurately identified due to the poor conditions of the present site, the stonework may be related to the building inside it. The back garden in Wanggung-ri Site, Iksan has a winding pond-shaped waterway to pull or push water into or out of the garden in a rectangular pond shape, which was a conventional landscape gardening technique during the Baekje period. Since the main garden and the back garden in Wanggung-ri Site, Iksan form a systematic connection system, this paper tried to newly establish the main garden inside Iksan Wanggungseong as the 'royal garden'.

The object of the study, Yousang-Dae(流觴臺) and engraved Go broad text on the flat rock in Gangneung-si Yungok-myun Yoodung-ri Baemgol, reveals that the place was for appreciating arts like Yusang Goksu and Taoist hermit's games. three times of detail reconnaissance survey brought about the results as follows. There is a the text, Manwolsan(滿月山) Baegundongcheon(白雲洞天), engraved on the rock in Baegunsa(白雲寺) that had been built by Doun at the first year of King Hungang(in 875) of the United Shilla, became in ruins in the middle of Joseon, and then was rebuilt in 1954. The text is an invaluable evidence indicating that the tradition of Taoist hermit and Sunbee(classical scholars) culture has been generated in Baemgol Valley. According to the 2nd vol. of Donghoseungram(東湖勝覽), the chronicle of Gangneung published by Choi Baeksoon in 1934, there is a record saying that 'Baegunsa in Namjeonhyeon is the classroom where famous teachers like Yulgok Lee Yi or Seongje Choi Ok were teaching' that verifies the historic property of the place. In addition, the management of Nujeong(樓亭) and Dongcheon can be traced through Baegunjeong(白雲亭) constructed by Kim Yoonkyung(金潤卿) in Muo year, the 9th year of Cheoljong(1858) according to Donghoseungram and the completed version of Jeungboyimyoungji(增補臨瀛誌). Also, Baegundongdongcheon(白雲亭洞天), the text engraved on the standing stone across the stream from Yousang-Dae stone, was created 3 years after the Baegunjeong construction in the 12th year of Cheoljong(1861), which refers a symbolic sign closely related with Yousang-Dae. Based on this premise and circumstance, with careful studying the remains of 'Yusang-dae' Goksuro, we discovered that the Sebun-seok(細分石) controling the amount and the speed of moving water and the remains of furrows of Keumbae-soek(擒盃石) and Yubae-gong(留盃孔) containing water stream with cups through the mountain stream and rocks around Yusang-Dae. In addition, as 21 people's names engraved under the statement of 'Oh-Seong(午星)' were discovered on the bottom of the rock, this clearly confirms that the place was one of the main cultural footholds of tasting the arts which have characteristics of Yu-Sang-Gok-Su-Yeon(流觴曲水宴) until the middle of the 20th century. It implies that the arts tasting culture of Sunbees had been inherited centering on Yusang-dae in this particular place until the middle of the 20th century. It is necessary to be studied in depth because the place is a historic and unique cultural place where 'Confucianism, Buddhism, and Zen'were combined together. Based on the result of the study, the identification of 23 people as well as the writer of Yusang-Dae text should be carefully studied in depth in terms of the characteristics of the place through gathering data about appreciation of arts like Yusanggoksu. Likewise, we should make efforts to discover the chess board engraved on the rock described on the documents, thus we should consider to establish plans to recover the original shape of the place, for example, breaking the cement pavement of the road, additional excavation, changing the existing route, and so fourth.

This study analyzed the hydraulic effects of Singok submerged weir in the lower Han River. 1-D hydraulic flood routing model was used and calibration and verification were performed using 8 flood or nonflood events. Flow characteristics were analyzed using various outflows of Paldang Dam and tidal data of the Yellow Sea. Water level increase effects by establishment of Singok submerged weir were as following, when maximum flood tidal was 2.4m, highest water level increased about 0.65m, and lowest water level increased about 1.25m in the downstream of Jamsil submerged weir. In Hangang Bridge, due to the Singok submerged weir, when maximum flood tidal was 2.4m, tidal range was 0.07m and decrement of tidal range was about $90\%$. And when maximum flood tidal was 5.5m, tidal range was 1.6m and decrement of tidal range was about $35\%$. When the outflow of Paldang Dam was over 20,000cms, tidal range was below about 0.06m, and tidal effect did not appear hardly.

행주대교 하류 약 3km 지점에 위치한 신곡수중보는 한강종합개발 사업 중 하도정비로 인한 상시수위 저하로 인해 발생하는 문제를 해결하기 위해 설치되었으며, 취수장의 취수심 확보, 주운수심 확보, 염수 역류에 의한 생태계의 변화 방지, 하천 주면의 지하수위 저하 방지 목적으로 건설되었다. 본 연구에서는 신곡수중보의 존치, 이전 혹은 철거로 인한 수질변화를 모의를 실시하였다. 한강 본류와 임진강 합류를 고려하여 총 495개 수질모의 셀을 구성하였고, 수질모의를 위한 WQ Cell은 길이가 100 m~340 m로 임진강 47개, 한강 448개로 총 495개의 셀로 구성하였으며, 주요 지천이나 오염원으로 신곡보 하류에는 공릉천, 신곡보와 잠실보 사이에는 창릉천, 서남과 난지물 재생센터, 안양천, 홍제천, 중랑천, 탄천, 잠실보 상류에는 왕숙천, 월문천, 덕풍천 등 9개 지천과 2개 물 재생센터를 포함하였으며 잠실보 상류에서의 생활용수 취수를 고려하였다. 수온, BOD, 조류의 경계조건은 환경부에서 제공한 2011년 3월과 4월의 측정자료를 사용하였다. 그 결과, 신곡보 철거시 수온의 변화는 서해로부터의 차가운 해수의 역류 증가로 임진강, 파주, 전류, 장항습지까지 수온이 최대 $0.94^{\circ}C$ 크게 하강할 것으로 나타났으나 행주, 가양, 영등포는 오히려 수온이 $0.03{\sim}0.04^{\circ}C$ 미미하게 상승할 것으로 나타났으며 현재의 신곡보가 수온의 급격한 변화를 완층하는 역할을 담당하여 왔으나 보가 철거되면서 이러한 수온 완충역할이 사라지기 때문으로 분석되었다. 신곡보 철거시 BOD 농도의 변화는 잠실보 하류쪽으로는 BOD 농도가 최대 1.02 mg/l 감소하는 등 전반적으로 수질이 크게 개선될 것으로 나타나는 반면 잠실보 상류쪽으로는 BOD 농도가 최대 0.56 mg/l 증가하며 현재의 1급수 수질에서 2급수로 수질이 악화되어 상수원 수질 관리가 어려울 것으로 예상되었다. 신곡보 철거시 조류 농도의 변화는 잠실보 하류쪽으로 조류 농도가 최대 1.85 mg-A/l 감소하는 등 전반적으로 수질이 크게 개선될 것으로 나타나는 반면 잠실보 상류쪽으로는 조류 농도가 최대 0.40 mg-A/l 증가하며 고조위 기간에는 조류주의보 기준 1.5 mg-A/l를 초과하는 경우도 발생하여 상수원 취수에 문제가 발생할 가능성이 있는 것으로 나타났다.

This article is the results of excavation data and it aims to interpret the composition facilities of the Royal garden at the Wanggung-ri site. The base of research was prepared through excavation and study on the royal garden at the Wanggung-ri site, which was constructed in Sa-bi period of Baek-je. The elements for the royal garden at the Wanggung-ri site were divided in 3 parts. - 1) Stonework facility 2) Installation for conveyance of water : Large moat-shaped ditch and Winding waterway(1~6 and water catchment) 3) Square cornerstone building. In this article, I arrange the basic data about facilities and function of the royal garden for making recovery of original form. First of all, I reason that stonework facilities were in charge to make space for catchment and boundary. Especially the Round angel rectangular stonework facility took charge of complex roles as catchment and water conveyance, and water can be transferred to the large moat-shaped ditch through joint between them. I confirmed that the round angel rectangular stonework facility and the large moat-shaped ditch which were connected by joint are one of the facilities in the royal garden. The large moat-shaped ditch protected the eastern, the northern walls and workshop site under the inclined plane to minimize the damage. Also, the large moat-shaped ditch took several roles, especially water catchments and landscaping. The large moat-shaped ditch was continually used from the period of Baek-je to the unified Silla, as a result it was completely deposited inside. After that, the 6 winding waterway were built in the western inclined plane with similar needs with the large moat-shaped ditch, and the square cornerstone building was built in same time. I noticed that the square cornerstone building was built as a part of the royal garden in Sa-bi period of Baek-je through the remains of Baek-je tiles around the building. After that, the square cornerstone building was built in same place as reconstruction.

In order to get the fundamental information that could be useful to judge the potentiality of occurrence of rapid shallow landslide in the objective slope, factors selected on Jinhae regions in Korea, where many landslides were caused by heavy rainfall of daily 465 mm and hourly 52mm in August 1979, was carried out through the multiple statistics of quantification method (II) by the electronic computer. The net system with $2{\times}2cm$ unit mesh was overlayed with the contour map of scale 1:5000. 74 meshes of landslides and 119 meshes of non-landslide were sampled out to survey the state of vegetative cover and geomorphological conditions, those were divided into 6 items arid 27 categories. As a result, main factors that would lead to landslide were shown in order of vegetation, slope type, slope position, slope, aspect and numbers of stream. Particularly, coniferous forest of 10 years old, concave slope and foot of mountain were main factors making slope instability. On the contrary, coniferous forest of 20-30 years old, deciduous forest, convex slope and summit contributed to the stable against Landslide. The boundary value between two groups of existence and none of landslides was -0.123, and its prediction was 72%. It was well predicted to divide into two groups of them.

In order to understand the relationship of depositional environment between fluvial and estuarine-embayment in Han River system, including depositional change in main Han River, more than 250 bottom sediment and 70 suspended sediment were analyzed with hydrologic data. Based on the previous data, the study area can be divided into two environment(fluvial and estuarine-embayment) by Singok underwater dam. The gravelly facies occurs in the South and North Han Rivers and sandy and silty facies occupies in the main Han River. Depositional environment of main Han River changed mainly because of limited sediment transport and hydrological condition. In the estuarine-embayment environment, coarse-grained sediments are dominant in tidal channel and of shore whereas fine and poorly sorted sediments are observed in coastal area. During moderate period, relationship between fluvial-estuarine-embayment system is discontinuou s because of flow restriction by artificial construction such as dam and underwater dam, so that each river system characterizes the individual environment. Fluvial and estuarine system is influenced by tide and, thus, transition zone of estuarine- embayment system moves landward. During flooding period, however, each river system is integrated as continuous depositional system by high discharge and, thus, transition zone of fluvial-estuarine-embayment system moves seaward. For further detailed systems about the lower Singok under-water dam, joint research of South-North Korea should be necessary.

In this paper, we propose a music search algorithm for automotive infotainment system. The proposed method extracts fingerprints using the high peaks based on log-spectrum of the music signal, and the extracted music fingerprints store in cloud server applying a hash value. In the cloud server, the most similar music is retrieved by comparing the user's query music with the fingerprints stored in hash table of cloud server. To evaluate the performance of the proposed music search algorithm, we measure an accuracy of the retrieved results according to various length of the query music and measure a retrieval time according to the number of stored music database in hash table.

This study is on Yun Seon Do's site located at Bogildo, Wando-gun, Jeonnam, compares the relics found through excavation to literature records and examines the character of relics and architectural features of the site. The results of this study are summarized as follows. First, bridge and pond including Goksudang and Seojae mentioned in related literatures were found around Goksudang. In the spatial composition, the area was divided into three using the stream from the valley and pond including buildings was built at each area. Each area was connected through Honggyo, Yueuigyo, and Ilsamgyo bridges and intentionally lengthened movement was considered as the space production technique to see the valley, and upper and lower pond. Second, 11 building relics, pond and fence were confirmed around Nakseojae. The transformative process of these relics could be divided into three periods. The 1st of these period was when Yun Seon Do lived there and Mumindang, pond and waterway were arranged as straight axis. Third, Dongcheonseoksil consisted of building relics (1) for preparing for and drinking tea and pavilion (building relics(2)) and pond, and these were static with nature and used as contemplative space for viewing.
